So I have seen comments that bitwardens extension works and want to check if no script does. Since libre wolf is just configuration I figure most stuff should work but not real sure. I looked to see if there was something like a pinned questions thread which I would normally put a minor question like this. Considering recent news maybe instead a moving from firefox pinned thread for awhile first.
I see a lot of posts from ToS refugees here, and I can guarantee you, the vast majority are going to be less happy with Librewolf than whatever the modern equivalent of Iceweasel is.
